Holding device with an antenna and method for assembling the same

Abstract

A holding device having a printed circuit board includes a base having a securing recess at a top surface thereof, a securing connector fixed in the securing recess and connected with the printed circuit board, a holding shell rotatably covered to the securing connector, and a flexible antenna of flat plate shape. The antenna has a rectangular radiating body, and a strip-shaped connecting portion extended outwards from a side of the radiating body. A free end of the connecting portion is held by the holding shell and rotated to connect with the securing connector electrically and detachably. An exposed portion of the connecting portion is bent so that the radiating body is attached to the top surface of the base.

What is claimed is: 
     
       1. A holding device having a printed circuit board, comprising:
 a base having a securing recess at a top surface thereof; 
 a securing connector fixed in the securing recess and connected with the printed circuit board; 
 a holding shell rotatably covered to the securing connector; 
 a flexible antenna of flat plate shape, the antenna having a rectangular radiating body, and a strip-shaped connecting portion extended outwards from a side of the radiating body; 
 a card, the card being inserted between the holding shell and the connecting portion, for electrically connecting the antenna and the securing connector after the holding shell is rotated to couple with the securing connector, 
 
       wherein a length of the connecting portion is substantially twice as the length of the card, a free end of the connecting portion is held by the holding shell and rotated to connect with the securing connector electrically and detachably, and an exposed portion of the connecting portion is bent so that the radiating body is attached to the top surface of the base. 
     
     
       2. The holding device as claimed in  claim 1 , wherein the exposed portion of the connecting portion is folded up according to the card and overlapped on the holding shell. 
     
     
       3. A holding device having a printed circuit board, comprising:
 a base having a securing recess at a top surface thereof; 
 a securing connector fixed in the securing recess and connected with the printed circuit board; 
 a holding shell rotatably covered to the securing connector; and 
 a flexible antenna of flat plate shape, the antenna having a rectangular radiating body, and a strip-shaped connecting portion extended outwards from a side of the radiating body, 
 
       wherein a free end of the connecting portion is inserted into and held by the holding shell detachably, a card is inserted between the connecting portion and the holding shell for electrically connecting with the connecting portion, a length of the connecting portion is substantially twice as the length of the card, the holding shell is rotated to couple with the securing connector, with the card electrically connecting with the securing connector, and an exposed portion of the connecting portion is bent so that the radiating body is attached to the top surface of the base. 
     
     
       4. The holding device as claimed in  claim 3 , wherein the exposed portion of the connecting portion is folded up according to the card and overlapped on the holding shell. 
     
     
       5. The holding device as claimed in  claim 3 , wherein the holding shell has a covering plate of substantially oblong shape, two first and second lateral plates are extended perpendicularly and downwards from two opposite sides of a front end and a rear end of the covering plate, the second lateral plates restrain the inserted card and the inserted connecting portion of the antenna. 
     
     
       6. The holding device as claimed in  claim 5 , wherein each of the first lateral plates has a front end extending forward to form a swingable arm, the swingable arms are pivoted to an insulating housing of the securing connector, for making the holding shell rotate with respect to the securing connector. 
     
     
       7. The holding device as claimed in  claim 6 , wherein each swingable arm has a free end protruded inwards to form a pivot, which is pivoted to a pivoting hole formed at each front end of two opposite sides of the insulating housing. 
     
     
       8. The holding device as claimed in  claim 5 , wherein a bottom edge of each second lateral plate is bent outwards to form a locking slice, for resting against a side of the securing recess. 
     
     
       9. The holding device as claimed in  claim 8 , wherein the bottom edge of each second lateral plate has a portion forward of the locking slice bent inwards to form a buckling slice for holding the inserted connecting portion. 
     
     
       10. The holding device as claimed in  claim 9 , wherein a top surface of the free end of the connecting portion has a stopping rib, the inserted connecting portion is extruded by the inserted card so that the stopping rib is buckled with front sides of the buckling slices for preventing the connecting portion from departing from the holding shell. 
     
     
       11. The holding device as claimed in  claim 3 , wherein the antenna is made of flexible printed circuit board. 
     
     
       12. The holding device as claimed in  claim 3 , wherein a top surface of the free end of the connecting portion has a stopping rib, two opposite lateral plates of the holding shell have portions bent inwards to form two buckling slices which block the stopping rib of the inserted connecting portion under the intrusion of the inserted card, for preventing the inserted connecting portion from departing from the holding shell. 
     
     
       13. The holding device as claimed in  claim 3 , wherein the top surface of the base has a receiving trough at a front end thereof, for receiving a battery, the securing recess is located rearward of the receiving trough, the radiating body lies on a top surface of the battery. 
     
     
       14. A method for assembling an antenna to a holding device, comprising the steps of:
 lifting a holding shell upwards; 
 putting a free end of a connecting portion of the antenna into a space formed by the holding shell; 
 inserting a card between a covering plate of the holding shell and the connecting portion, a length of the connecting portion being substantially twice as the length of the card; 
 rotating the holding shell to cover an insulating housing of a securing connector; and 
 folding an exposed portion of the connecting portion to overlap on the holding shell, with a radiating body attached to a top of a base. 
 
     
     
       15. The method as claimed in  claim 14 , wherein the connecting portion is pulled outwards a distance after the card is inserted, for electrically connecting with the inserted card.
